I'm pretty sure the carbon filters use activated carbon, yes?
Does anyone know where you can buy a bag of this stuff to refill - googling just gives me a bunch of pet and fish tank items by the ounce.
What do you guys use to replenish your carbon filters?
Hose it down real good... let it dry.
GOOD AS NEW!
Really? The carbon doesn't ever get "used up?" I guess I don't completely understand the science behind it.
I have the same filters for 8yrs now... im no scientist however it does recharge the carbon... try it, you have nothing to loose.. by me a beer later! lol
One more thing...when im done rinsing mine down, i put the fans back on em and they are dry within an hour
but if they do get gunked up, then could you not just wash them again? and would they not be degunking your grow room?Regarding putting your fan back on it immediately, I imagine more dust and particulates will get gunked up in the carbon doing this. I've done it like that and then just opted to let it air dry, which doesn't take long with 15% humidity in your house
